How to Run and Read an Aircraft Lien Search Before You Buy
For buyers who want to know what a title and lien search actually looks at, how to read the report entry by entry, and what to do when something on it isn't released.
What does an aircraft lien search check?
The FAA describes each aircraft record as three things: the registered owner, recorded security interests, and airworthiness information. It also says plainly that "the FAA does not perform title searches" (FAA: Clear Title). A search means reading that record, and sometimes records outside it.
| Source | What it shows | What it misses |
|---|---|---|
| FAA N-number lookup (free, online) | Registered owner, address, aircraft data, registration expiration | Lien analysis; you can't tell from it whether a loan was released |
| FAA document index | Which documents the Registry has received for the aircraft | The documents' contents |
| Full FAA aircraft record ($10 CD-ROM) | Bills of sale, security agreements, claims of lien, releases, court orders, and airworthiness documents such as Form 337s | Liens that were never filed with the FAA |
| International Registry | International interests under the Cape Town Convention | Irrelevant for most pistons. It covers only airframes certificated for 8 or more persons including crew or more than 2,750 kg of goods, and engines of 550 hp or more |
| State and county records (add-on) | Federal and state tax-lien notices, judgments, UCC filings against the seller | Anything tied to the aircraft but filed elsewhere |
| The aircraft itself | Whether a shop is holding it for an unpaid bill | Nothing on paper; you have to ask and look |
How to run the search: yourself or through a title company
Doing it yourself
- Look up the N-number on the FAA Registry site. Confirm the make, model and serial number match the aircraft's data plate, and that the registered owner is the person or company selling to you.
- Check the document index for recent filings that may not be examined yet. As of late September 2026 the Registry was processing documents received around mid-June, so a filing made this summer may be in the file but not yet recorded.
- Order the complete aircraft record. The FAA charges $10 per CD-ROM, or $0.10 per page on paper. The average record runs about 76 pages. Certification is another $10 and is usually needed only in court.
- Work through the record in date order and pair every security agreement or claim of lien with its release. Anything left unpaired is open.
Using a title company
Aviation title companies, many of them in Oklahoma City near the Registry, search the record, report the chain of title and open liens in writing, and often handle the escrow too. FLYING Finance (July 2026) puts a typical search at one to three days. Fees vary by provider and by how messy the record is, so get a written quote. Most lenders order their own search, or use the closing agent's search, before they fund.
Decision rule: do a DIY pull to screen an aircraft before you make an offer. Get a professional search, plus an update just before funding, before any money goes to the seller.
How to read a title report, line by line
Below is an illustrative record for a 1978 Cessna 182Q. The parties are fictional, but the patterns are the ones that come up most often.
| Entry | Filed | Release on file? | What it means |
|---|---|---|---|
| Security agreement: prior owner to Heartland Savings | 2008 | No | A stale lien. The loan was probably paid when that owner sold, but no release was ever filed. It must be cleared. |
| Bill of sale: prior owner to Westfield Flyers LLC | 2014 | n/a | A chain-of-title link. It is fine if the seller names match the record. |
| Security agreement: Westfield Flyers LLC to First Prairie Bank | 2014 | Yes, 2019 | Clean. It was paid off and released. |
| Bill of sale: Westfield Flyers LLC to Karen J. Ostrow | 2019 | n/a | The current owner. She must sign your bill of sale as "Karen J. Ostrow". |
| Security agreement: Ostrow to Lakeshore Credit Union | 2019 | No | An active loan. Get a payoff letter and have it paid and released at closing. |
| Claim of lien: Tri-County Aero Services, $6,850 | 2025 | No | A shop lien for unpaid work. Get the invoice, then settle and release it before or at closing. |
Three items must be cleared before you have clear title: the 2008 Heartland lien, the Lakeshore loan and the Tri-County claim. A lender will make all three closing conditions. You should too.
Red flags that should stop the closing until resolved
- The seller is not the registered owner, or signs under a different name or entity.
- A gap in the chain: a bill of sale into the seller from someone who never appears as an owner.
- The serial number or model in the record doesn't match the data plate.
- Any claim of lien from a repair shop, fuel vendor or hangar owner.
- A registered owner who has died. The registration ends 30 days after the owner's death, and the estate must sell.
- A registration that has expired, or expires within the next few months.
- Court orders, divorce decrees or bankruptcy filings in the record.
Mechanic's liens, tax liens and liens the FAA record may miss
The FAA records documents but does not decide whether they are valid. In its words, "state law determines lien and security interests." That matters for three kinds of claims:
- Mechanic's (artisan's) liens. Most states give repair shops a lien for unpaid work. Depending on the state, the shop keeps possession of the aircraft, files a notice with a state or county office, or files a claim of lien with the FAA. Deadlines and priority vary. Ask the seller for paid invoices from the last annual and any recent shop visit, and get a written statement that no work is unpaid.
- Tax liens. The FAA's definition of clear title includes tax liens on record against the aircraft. A federal tax lien, though, attaches to all of a taxpayer's property, and its notice is generally filed in state or county offices, not with the FAA. If the seller is a business in distress, add a tax-lien and judgment search where the seller is located.
- UCC filings. For a U.S.-registered aircraft, the FAA filing, not a state UCC-1, is how a lender perfects its lien (UCC 9-311). Some lenders file a UCC-1 anyway, so a state search can surface one. Ask for a UCC-3 termination along with the FAA release.
Which lien wins when there are several is a priority question, covered in how lenders perfect an aircraft lien.

How to clear an old lien that was never released
- Identify the secured party today. Banks merge and rename. The successor institution owns the old loan file and can sign the release.
- Request a release in the FAA's format. The FAA accepts the original AC Form 8050-41 Conveyance Recordation Notice signed by the secured party, or a document that identifies the collateral and the lien and releases all of the lienholder's rights. Both must be signed in ink.
- Replace a lost 8050-41. The Aircraft Registration Branch, at (866) 762-9434, can help the secured party get a new notice.
- Failed lenders. For a failed bank, the FDIC, as receiver, handles lien-release requests for many failed institutions. Start there before hiring counsel.
- No one to sign. If the lender dissolved and has no successor, an aviation attorney may need a court order to clear the record. Budget time, not just money.
- Protect the closing. If the release is promised but not in hand, have escrow hold back enough of the seller's proceeds to cover it, or delay closing. Don't accept a verbal assurance.
Clearing title is normally the seller's job and the seller's cost. Say so in the purchase agreement.
Paying off the seller's loan at closing: a worked example
The seller's Lakeshore Credit Union loan has a principal balance of $142,300 at 7.5%. Interest accrues at about $29.24 a day. The payoff letter is good through a date six days after it is issued, so the escrow agent needs $142,475.44 to retire it on that date, plus any fees the letter lists.
- Escrow wires the payoff directly to the credit union, never to the seller.
- The credit union signs the release and sends it to escrow before, or in exchange for, the payoff.
- Escrow files the release in the same package as your bill of sale, registration application and your lender's security agreement.
- The seller receives only what is left over. If the payoff is more than the price, the seller brings cash to closing.
What does an aircraft lien search cost, and how long does it take?
| Item | Cost | Time |
|---|---|---|
| FAA record on CD-ROM (DIY) | $10 per aircraft | Depends on Registry turnaround; order early |
| Professional title search and report | Varies by provider; get a written quote (often bundled with escrow) | Often 1–3 business days; rush available |
| Update just before funding | Often included; confirm | Same day or next day |
| State tax-lien, judgment and UCC searches | Extra; quoted per state | A few days |
| Clearing a stale lien | Seller's cost; legal fees if a court order is needed | Days (cooperative lender) to months (defunct lender) |
After closing, check your own record
- Within a few weeks, confirm the documents appear in the document index: the seller's releases, your bill of sale, your application and your lender's security agreement.
- When the certificate arrives, check that your name, address and the aircraft's serial number are correct.
- When you pay off your own loan, make sure the release is filed. An unreleased lien becomes the next buyer's problem, and it will surface on their search.

Frequently asked questions
Can I do my own aircraft lien search?
Yes. The aircraft record is public. The FAA says it does not perform title searches, but you can order a copy of any aircraft's record on CD-ROM for $10 and read the bills of sale, security agreements and releases yourself. That works well for screening. Once money is about to move, or a lender is involved, have an aviation title company search and report in writing.
Does the free FAA N-number lookup show liens?
Not in a form you can rely on. The N-number lookup shows registration details such as the owner, address and expiration date. Recorded liens and their priority can only be determined by reviewing the documents in the aircraft record itself. Order the full record, or a professional search, to see which security agreements were filed and which were released.
How long does an aircraft title search take?
A routine search by an aviation title company is often back within one to three business days, and rush service is common. The slow part is clearing problems. A payoff and release on an active loan can happen at closing. An old lien from a bank that merged or failed can take weeks or longer, so order the search as soon as the purchase agreement is signed.
What happens if the search finds a lien the seller did not disclose?
Stop and resolve it before any funds go to the seller. Ask for the payoff or the release. If it is a paid-off loan that was never released, the seller gets a signed release from the lender. If it is a shop's claim of lien, the seller pays it from proceeds or settles it. A well-drafted purchase agreement makes clear title a closing condition and lets you walk away if the seller can't deliver it.
Will an FAA search find a mechanic's lien or IRS tax lien?
Sometimes. The FAA defines clear title as no unreleased security agreement, tax lien, artisan lien or similar document on record, so some of these are filed with the Registry. Others exist only under state law, through a shop keeping possession of the aircraft, or in state and county records where the seller lives. For a seller with warning signs, ask the title company to add state tax-lien, judgment and UCC searches.
How do I remove an old lien that was paid off years ago?
Ask the lender, or its successor after a merger, to sign a release. That can be the original AC Form 8050-41 Conveyance Recordation Notice or a letter that identifies the lien and releases all its rights, signed in ink. Then file it with the Registry. For a failed bank, the FDIC, as receiver, handles release requests for many failed institutions. If nobody with authority can be found, an aviation attorney may need a court order.
General information, not legal advice. Lien validity and priority depend on state law. Use an aviation title company or attorney for any unresolved item.
